Two unpopular AC/DC albums I like are Fly On The Wall and Blow Up Your Video. Whilst the production sense they are average albums, musically they each have some pretty decent songs. Under rated albums although not as criminally under rated as Flick Of The Switch. That album gets more listens from me than Back In Black which is often beaten to death.
"Fly On The Wall" & "Flick Of The Switch" are actually my two favourite AC/DC albums! I prefer them to the staples like "Back In Black" & "Highway to Hell" (I also
slightly prefer Brian Johnson to Bon Scott .. hehe..). I thought "Blow Up your Video" was excellent...so was later stuff like "The Razor's Edge" & even "Ballbreaker".
Anyway, unpopular albums I like would be..
..anything by Yngwie (lol!)
Testament's "The Ritual" & "Low"
Nuclear Assault's "Something Wicked This Way Comes"
Flotsam & Jetsam's "Quatro"
Maiden's "The X Factor" (Songs off it sound especially great live with Dickinson singing them..
)
Manilla Road's "Out OF The Abyss" (Sure, it was a departure for them, but what an AMAZING departure!)
Napalm Death's "Harmony Corruption"
Nocturnus's "The Ethereal Tomb"
Crimson Glory's "Astronomica"
All GREAT albums as far as I'm concerned..
